Executive Summary:
The Public Works Department is nearing completion of the pre-construction efforts for Phase 1 of the South Main Street and Soda Bay Road Corridor Improvement Project and requests authorization to advertise the project for construction bids.
The overall project (collectively Phase 1 and Phase 2) extends approximately 1.25 miles, from the Lakeport city limits along South Main Street to the intersection with State Highway 175 and Soda Bay Road, then south on Soda Bay Road toward Manning Creek. The project will reconstruct and widen the roadway with two 12-foot travel lanes, a continuous 12-foot center turn lane, and 8-foot paved shoulders/Class II bicycle lanes; improve drainage; install water infrastructure; and relocate existing overhead utilities underground.
Phase 1 includes the full length of South Main Street within the project limits and a short portion of Soda Bay Road immediately south of the intersection with State Highway 175. The remaining Soda Bay Road improvements will require a future phase as additional funding becomes available.
